This volume outlines a frequency plan that can generate all the required frequencies from a single fixed frequency, able to implement center frequencies with no more than two levels of SSB mixing. It recognizes the need for future synthesizers to bypass on-chip inductors and operate at low voltages to enable the increased integration and efficiency of networked appliances. The author examines in depth the architecture of the dividers that generate the necessary frequencies from a single base frequency and are capable of establishing a fractional division ratio.   Presenting the first CMOS inductorless single PLL 14-band frequency synthesizer for MB-OFDMUWB makes this volume a key addition to the literature, and with the synthesizer capable of arbitrary band-hopping in less than two nanoseconds, it operates well within the desired range on a 1.2-volt power supply. The author’s close analysis of the operation, stability, and phase noise of injection-locked regenerative frequency dividers will provide researchers and technicians with much food for developmental thought.Very high speed integrated circuitsMetal oxide semiconductors, ComplementaryVery high speed integrated circuits.Metal oxide semiconductors, Complementary.621.3815621.39/732Farazian Mohammad1064245Gudem Prasad S1064246Larson Lawrence E28445MiAaPQMiAaPQMiAaPQBOOK9910437909303321Fast hopping frequency generation in digital CMOS2537155UNINA
